Black Manta is a supervillain appearing in American comic books published by DC Comics. The character was created by Bob Haney and Nick Cardy, and first appeared in Aquaman #35 in September 1967. He has since endured as the archenemy of the superhero Aquaman.

Black Manta has had numerous origin stories established throughout his comic book history, having been a young boy kidnapped and enslaved by abusive pirates on their ship; a child subjected to experiments in Arkham Asylum; and a ruthless mercenary caught in a mutual cycle of vengeance with Aquaman over the deaths of both their fathers. Despite these differing versions of his past, Black Manta is consistently depicted as a cutthroat underwater villain who uses a high-tech armored suit in his obsessive quest to destroy Aquaman's life.

The character has been adapted in various media incarnations. Yahya Abdul-Mateen II portrayed Black Manta in his live-action cinematic debut in the 2018 DC Extended Universe film Aquaman, and will reprise the role in the upcoming 2023 sequel Aquaman and the Lost Kingdom. Kevin Michael Richardson, Khary Payton and others have provided the character's voice in media ranging from animation to video games.
